Application filed March 10, 1919.

have invented certain new and useful Improvements in Grease-Cups, of which the following is a specification.

This invention relates to an improved grease cup, and has for one of its objects to prevent detachment of the cup from the bearings orother support to which it is attached, said detachment often being accidental or caused by vibrations of the bearings.

Anotherobject is to provide a grease cup which will be convenient in use and may be i adjusted to cause a pressure of the grease in a direction of the bearings, and to consist of few and simple parts so that it may I be economically manufactured.

. In the accompanying drawing Figure 1 "is a view of the grease cup in longitudinalsection showing it applied to the conducting tube of a bearing. Fig. 2 is a bottom plan view of the grease cup. Fig. 3 is a bottom plan view of a locking-disk. Fig. 4

is a broken away view showing the lower part of the grease cup. Fig. 5 is a broken away side view of the locking disk. Fig. 6

' is a bottom plan view of the grease cup and locking disk when assembled, to show relative position of parts.

Referring now to the drawing, numeral 7 indicates a shaft mounted for rotation in its bearings 8, said bearings being provided 7 v with an exteriorly threaded tube 9 for conducting grease to the shaft.

We provide a cylindrical grease cup 10 having a bottom (1 provided at its middle with a threaded "aperture 6 and also pro- 7 vided with a lug c which projects outwardly from said bottom near or closely adjacent to the aperture 6. In the drawing, the lug c is shown to be provided with threads, but while this construction is preferred, it is not important, and the threads for the lug 0 may be dispensed with if desired.

Numeral 11 indicates a locking-disk provided at its middle with an interiorly threaded aperture 03 and also provided with a recess 6 opening on its aperture, said recess having a wall f non-concentric with th threaded wall of the aperture 01.

Since that part of the tube 9 outwardly "of the bearing 8 is exteriorly threaded, the

grease cup and disk may be mounted thereon and may be rotated for moving the cup. longrtudlnally of said tube, the lug 0 being disposed loosely in the recess 6 of the locking disk to that part of the wall f of its recess e farthest remote from its center, and it w1ll be understood that when the lug c is disposed in that part of greatest area of the recess 6, the cup and disk may be simultaneously rotated to move the grease cup longitudinally of the tube 9, but if the disk is rotated to cause the wall 7 of its recess e to engage the lug c of the grease cup, a revoluble movement of the grease cup will be prevented since the threaded wall of its bottom a will be pressed against the tube 9, and therefore the grease cup may be secured in stationary relation with said tube, and may be adjusted longitudinally of said tube.

Numeral 12 indicates an annular flange which is removably mounted upon the end of the tube 9, its area being approximately equal to the area in plan of the chamber 13 of the grease cup. An adjustment may be made of the grease cup so that the flange 12 will be disposed in the lower part of the chamber 13, and the lid 14 being removed, the cup may then be filled, and after the lid has been replaced, adjustments may be made of the grease cup longitudinally of the tube 9 to cause a pressure of the grease, the consistency of the latter being such that this feature is of advantage for moving the grease through the tube 9 to the shaft.

We claim 1. In a grease cup, a conducting-tube, a receptacle communicating, with the tube, said receptacle having a bottom provided with an outwardly projecting lug and having a threaded aperture in engagement with said tube, a disk having a threaded aperture also in engagement with the tube and having a non-concentric recess for receiving said lug, said disk being revoluble for engagement of the wall of its recess with said lug for pressing the bottom of the receptacle against the tube to maintain said receptacle in stationary relation with the tube at longitudinal intervals thereof.

2. In a grease cup, a conducting pipe having an annular flange, a receptacle circmn-r scribing the annular flange andcommun'icat ing With said pipe, said receptacle having its 7 I cess With s 5 bottom provided With an outwardly pr0ject-' signatures in presence of two Witnessesf ing lug and having a threaded apertureiii CLAUDE M. :SKINNER; engagement with said pipe, a disk having J p ROY, J.
